Application June 15, 1939, Serial No. 279,277 7 claims. (ci. isi-6.7)

This invention relates to a marking means or apparatus and has for one object to provide an assembly of type bars or marking members and means for operating them. Another object is to provide an assembly of type bars in which the means that carry the bars are arranged for ready and economical assembly with the bars. Another object is to provide means for moving the type bar assembly. A still further object is to provide means for supporting a member which is to be marked and for moving the supporting means in synchro'nism with the type bar as# sembly.

Other objects will appear from time to time throughout the speciiication and the claims,

The invention is illustrated more or less diagrammatically in the accompanying drawings, wherein:

Figure 1 is a plan view with parts omitted and parts broken away;

Figure 2 is a transverse, vertical section on a reduced scale taken at line 2 2 of Figure l and showing parts additional to those illustrated in Figure l;

Figure 3 is a side elevation of one of the type bars or marking members;

Figure 4 is a bottom plan view of the type bar of Figure 3; Y v

Figure 5 is a bottom View of the type bar retainer.

Like parts are designated by like characters throughout the speciiication and the drawings.

While the type bar carrier or assembly is shown as associated with other parts-particularly, those for carrying a member to be marked and for moving that member and the type assembly-the type assembly itself could be associated with other moving, positioning and carrying members.

The type assembly comprises a main carrier I. As shown, this carrier is relatively disc-shaped. It is provided along its upper edge with a ange 2 which is slotted or notched as at 3 to receive the various type bars. Positioned inwardly from its edge is an annular upstanding flange 4 which is slotted as at 5. For each slot 3, there is a corresponding slot 5, the two being positioned upon a single radius. The disc-like member I is attached to and preferably integral with a hub 6. A plurality of enlargements 'I may be formed integrally with the hub and with the disc I. Upstanding enlargements 8`may, also, be formed and they terminate at their upper ends in shoulders or projections 9. The members 8 may be omitted and, instead, a shoulder might be formed about the hub 6. The purpose of the projections 9 or the shoulder which is suggested is to furnish both a seat and a limit for the typebar retaining member l0 which is positioned upon the shoulder or upon the projections 9 and held in placeby I screws I I which pass through corresponding per-v forations I2 in the member I0 and are engaged in suitably threaded perforations or sockets in the enlargements 1. Obviously, other means might be substituted for the screws, but the construction shown is convenient. The retainer Il] carries a downwardly facing, peripheral flange i3 which engages the type bars in a manner de' scribed below. The disc-like memberI is provided on its lower surface with an enlarged and -preferably annular portion I4 Within which are formed sockets I5. The sockets I5 are formed one for each type bar and each socket is, thus, preferably radially aligned with a pair of grooves 3, 5. Within each socket is positioned a spring I6. If desired, the outer edge of the carrier may be provided with centering and positioning means. In the particular` form here shown, this means includes outwardly facing teeth I1 whichare formed peripherally in the enlargement I 4.

They might be otherwise positioned.

The marking members, which in the form'here shown are type bars, comprise bar-like members I8, each of which is provided in its upper surface with a rounded notch I9. Each type bar is positionedso that it extends through pairs of grooves 3, 5 and over a spring I6. The type bars may be cut away as at 20 and carry type faces or type members 2|. As here shown, the type members are sunk. They might project outwardly but the invention is not limited to any particular arrangement of type. bols, letters, numerals or the like may be used.

The flange I3 of the retainer Ill its into the grooves or notches i9 and the type bars are, thus, held in place. They rotate up and down about the flange I3 as a fulcrum. The flange I3 may rest upon the upper edge of the member 4 as illustrated in Figure 2 in particular. The disc-like member may be flat or of any desired shape. As

shown, particularly in Figure 2, it has a depression 22 adjacent the hub and adjacent the enlargements 'I and the inner ends of the type bars lie in this depression. The inclination of the surface of the depression may be such that when the type bars are in the raised position-that is to say, the full line posltion of Figure Z-their bottom surfaces adjacent their inner ends lie flat or flush upon the surface of the depression 22.

As above noted, the type bar assembly may be used in several associations and with dilierentl Of course, any desired symis, indica-ted diagrammatically at.-

carriers and means of rotation. In the one illustrated, however, the hub 6 is secured to a shaft 23 by a key 24 so that it turns with the shaft. A collar 25 may, also, be positioned about the shaft and held in place by a set screw 2S. The shaft may be of any desired length and may lie Within a bar 21. Any desired means for rotating the shaft may be used. As shown, a beveled gear 28 is secured upon the shaft. It might mesh with another beveled gear through which the shaft' could be rotated.

At its lower end the shaft is received in a bearing 29 formed in a frame or base member 3|) which forms part of the total machine. EX.-A tending upwardly through the machine is a bracket 3| within which is journaled4 at'32f a, hammer arm 33. At one end, the hammer arm carries an upward projection 34which may strike against a shock absorber 35 which is itself adjustably mounted in an extension 36. ofv the bracket 3|. At` its opposite end, the-hammer4 armcarriesa) hammer head 3,1. Anextension. 3 8,fr.orn theyhammer, head may be providedi 3 9, isalifting, means, thefdetails. of. which are not. here, shown since they form no essential, part of, the `present invention. Byj. anyY suitable means, the lifting member 39 may be raised., to. raise` the. hammer and may be freed. to. permit the hammer.- to fall. The hammer preferably has a. striking point or extension. 40- of suitable size and., shape to strike a. single type bar, |8w-hen thehammer: is released for falling. When this. occurs,:the-type bar will be forced. downwardlyv against.. the resistance of itsspring I6 andan impression will, be made, provided a suitable article has beenmoved into position tobe contacted by the type bar.

One means. for carrying an article to bev marked `is shown-in Figures 1v and'2. Thisv means comprises an.- anvil 4| which restsv upona base 42;. The anvil,v as shown, is receivedwithin a. rotary housing 43 towhichit is connectedby. a key,44-so, that4 the two rotate together. Secured, to thehousinglill. is a ratchet'451by'means of which the housing 43 andianvil; 4|A mayk be,- rotated.` The housingA ismountedfor rotationv in a-bearing, portion 46 ,which may,` as here showni, beintegral with, the support orV frame member., 35;.` Adjacent its upper end, ther housing.; member; 43.- carries a centeringand receiving, ring., 4.1,V whichisroundedor beveledat its inneriedge as at 48 and removablyy held in, placel on.v the, housingy 43-l by. screws 43 or, otherwise.

A spring abutment 6i) is formed on the lever 51 and a spring 6| bears at one end upon this abutment and at the other end upon the abutment 55 of the lever 53.

rnose1|l of the dog 65 may engage the teeth of the ratchet45.

The type carrier is provided with teeth I1 and the centering nose 55 of the lever 53, which is held against the type carrier by the spring Bl, properly centers each type member. When the assembly is rotated, the lever 53 moves counter clock-wise as the spring 6I yields. v

As shown, the type carrier is preferably made by a single die-casting. The type bars are readily assembled in the grooves or notches provided in the members 2 and after the springs IS have been put in place. With the springs and type bars suitably assembled, the holding or retaining member ID is fastened in place. Shoulders 9 or similar parts are provided to prevent the retainer being pushed down too far in assembly. If this were to occur, it would interfere with the proper reciprocation of the type bars. The type bars turn about the flange i3 of the member lil which rests within the notches I9; the flange I3, thus, serves as a fulcrum point. The details of the token-carrying mechanism and the means for moving it to and from the anvil and housing are omitted as they form no essential part of the present invention, which is not limited to any particular token or token-handling means.
